The Institute for Health Services Research and Health Economics (ISE) studies the demand for and utilization of health care services, health care structures and processes, and their clinical and cost-effectiveness, in particular under everyday conditions and considering patient needs and preferences.
It thereby contributes to the development, evaluation and implementation of targeted, efficient interventions in compliance with international standards.
The ISE is responsible for the ‘Patient-relevant aspects and health economic evaluation of diabetes prevention and treatment’ research program, which it implements in cooperation with the other DDZ institutes.
The ISE working groups are tightly interlinked. Close ties are maintained with the Institute for Health Services Research and Health Economics at the Centre for Health and Society of the Medical Faculty of the Heinrich Heine University.
The ISE is also committed to greater involvement of patients and citizens in research. The ISE is continuously looking for interested people to work as co-researchers together with scientists in research projects. In this context, a citizens' advisory board was also founded.

The ISE is active both nationally and internationally in working groups, at events to promote young scientists, etc.
Mt. Hood Meeting
The Mount Hood Diabetes Challenge Network is dedicated to promote an exchange of ideas and information between those developing and using health economic diabetes simulation models. It has run a diabetes computer simulation modelling conference bi-annually since 1999. A major focus point of the conferences is the comparisons of health economic diabetes models both in terms of their structure and performance.
In 2018, the Mt Hood Meeting was hosted by researchers of the ISE at the German Diabetes Center (DDZ).
Workshop for Early Career Investigators in the Field of Health Services Research
4th Workshop for Early Career Investigators in the Field of Health Services Research in Düsseldorf at the Centre for Health and Society at Heinrich Heine University
In 2017/2018 the fourth Workshop for early career investigators “Health Services Research” established by the DFG (Deutsche Forschungsgemeinschaft) took place at the German Diabetes Center in Düsseldorf. The Workshop for Early Career Investigators was hosted by the Centre for Health and Society (chs) at the Heinrich Heine University in cooperation with the Center for Health Services Research of the University of Cologne (ZVFK), the Interdisciplinary Center for Health Services Research (IZVF) of the University of Witten/Herdecke, the Research Centre for Health Communication and Health Services Research at the University of Bonn, and the Institute for Health Services Research and Clinical Epidemiology of the University of Marburg.
The aim of health services research is to explore the daily routine of health care, to improve processes and to help ensure that suitable offers are made for all patients.
The workshop gives outstanding early career investigators in this field the opportunity to develop innovative project ideas and research projects.
EASD Study Group on Health Services Research and Health Economics
The second meeting of the EASD (European Association for the Study of Diabetes e.V.) Study Group on “Health Services Research and Health Economics” was held at the association’s 55th in Barcelona. The group was initiated by the ISE in 2018 under the leadership of Andrea Icks and is coordinated by the ISE team.
Despite the great importance for diabetes research, the EASD did not have a working group looking into health care research and health economics subjects before 2018. The group aims to pool, extend and further develop existing research activities. This includes patient-centered health care, in particular patient preferences in diabetes treatment. A further key area of work are health economic models about diabetes complications. The EASD Study Group seeks to act as an exchange platform for clinicians and researchers from diverse fields (health economics, health care research, epidemiology), and in the future also a platform for patients.
Patient and public involvement in research
Since 2020 we have been working together with patients and citizens as co-researchers to further expand involvement of patients and citizens in our research (participatory health services research). Taking into account their individual resources, interests and abilities, they conduct research in collaboration with us in research projects relevant to health service provision. In addition, joint research projects are planned. Our activities include (1) patient and public involvement in research projects, as well as (2) the establishment of structures to expand patient and public involvement.
Patient and public involvement in research projects
Patient-centeredness is a key criterion to ensure high-quality care in the future. By involving patients and citizens in research projects, the research should be more closely oriented to the everyday life of the people whose living environment is to be researched. A joint examination of different perspectives can create a learning process for all participants. In addition, we regularly involve patients and citizens in the development of questionnaires.
- Patient and public involvement in the GestDiNa project (aftercare for gestational diabetes)
- Assessment of information needs amongst people with diabetes mellitus in different stages of the disease
Establishment of structures to expand patient and public involvement
The establishment of the citizens' advisory board in September 2020 was another important step towards expanding and establishing patient and public involvement in research of the ISE in the future.
The citizens' advisory board receives information on the research projects of the ISE and advises the ISE in order to take greater account of opinions, wishes, concerns, fears and expectations of the public in research, to better identify existing gaps in research, to support the expansion of participatory research and to increase public understanding and awareness of diabetes research.
The citizens' advisory board is currently composed out of four citizens with different personal and/or professional relations to the disease of diabetes.
Members of the citizens' advisory board at the ISE are:
- Evelyn Bruns, voluntary leader of the diabetes support group at DDZ, Düsseldorf and professional employee of the Centrum für Integrierte Diabetesversorgung (CID), Cologne
- Nicola Irmer, artist, Düsseldorf
- Christoph Rupprecht, head of health policy and health economics department, AOK Rhineland/Hamburg – Die Gesundheitskasse, Düsseldorf
- Hartmut Wecker, head of communication, district Waldeck/Frankenberg
Interested in doing research together with us? You are welcome to contact us!
We are continuously looking for interested patients and citizens for smaller and larger projects. We know from previous projects that both groups have valuable ideas and expertise in research projects. Furthermore, we would like them to participate, as health care directly affects them. If you are interested, please contact Sandra Borgmann (firstname.lastname@example.org).
